ORTHODONTIA-PLLERS.

To all whom t may concern:

Be it known that l, llflA'rrHnw N. FEDER- srinn, a citizen of the UnitedStates, residing at lvlilwaulee, in the county of Mil wanliee and Stateof wlllisconsin, have invented a new andV usel'ul Improvement in`rthodontia-lliers, of which the following is a specilication.

'll/.ly invention relates te certain new and 'useiul improvements inorthodontia pliers, and is tnlly described and explained in thesjgiecilication and shown in the accompanyirre,I drawing, inwhichll'igure l is a side elevation of iny iniproved device, oneliurcation of the bi'lini cated aw being` broken away; Fig. 2 is anelevation looking from the lett oi.E Fig. l.; litigi'. 3 is a viewsimilar to Fig. l with the jaws open; lfig. l is a section on the line lof 2, and Fig. 5 is an elevation et the work done by the device.

teilerring to the drawings, G and 7 are two jaws adapted to oppose eachother and nmtually pivoted so as to be opened and closed by the handlesprovided as in any ordinary pair of pliers. The aw G is provided with aprojecting rib composed el several parts 8, 9, l0, ll and l2, oligradwilly decreasing width in the plane of the jaw and the port l2 beinglower than the parts 8 and 11, inclusive, as shown in Figs. l. and 'lhejaw is bilrlrcated to straddle the rib on the jaw G, the space betweenits :liurcations being' inade progressively narrower troni the endtoward the pivot, so that when the jaws are closed together, each partof the iurcations is spaced at substantially an equal distance from theadjacent part oit' the rib.

rlhe several parts of the rib on the jaw G are provided with notches 13to engage and center the wire which to be nsed.

rlhe operation oli the device will be readily apparent. A piece of wireof the sort connnonly employed in Orthodontie work is placed across thatpart of the rib of the proper width to furnish the desired interiorspacing` in the bend te be made. The jaws are then brciiight togetherand the wire is not only bent into the loop torni, but the Specificationof Letters Patent.

parts adjacent te the loop are engaged between the plane surfaces of thejaws so as to turn theni out into a perteetlystraight line. lt is thuspossible to make bends et live ditierent sizes, as illustrated, and ineach case the bends are perfectly proportioned and the original straightline of the wire is maintained.

l realize that considerable variation is possible in the details ol theconstruction. heroin shown, and l do not intend to liniit niyselfthereto, except pointed out in the following clainis, in which it is niyintention te claini all the novelty inherent in the device as broadly ispermitted by the state ot the art.

l claini as new and desire to secure by Letters Patentll. A device oitthe class described co1nprisingtwo opposing plane jaws, a rib piojectine1 troni one jaw and consisting olib a series ol separate parts ofdill'erent widths, the other jaw being bilurcated to straddle the riband having the space between its furcations oil various widthscorresponding te the width ot the rib parts.

2. Orthodontia pliers having opposing plane awe, a rib on one awconsisting of a series oi parts (lilies-inn, in width. and height, theother jaw beingl bilinrcated to straddle the rib and hai/ing the spacebe tween its furcations oit diliferent widths correspond in p; to thedillerent rib parts, ior the purpose set lorth.

3. it device et the class described. co1nprising two opposing planejaws, a rib pro jeeting;` trein one jaw and consisting of a series oi?separate parts of dili'erent widths, the other jaw being),` bifnrcatcdto straddle the rib and having the space between its iiiufcations etvarious widths corresponding to the width of the rib parts, the said ribparts being' provided with notches to hold the niaterial ope ated upon.

ln testimony whereof l have hereunto set .my hand this th day oit June,191%.
